I believe that fanapt is the new risperdal with tweaks. I was on it for a week in 2014? before giving up and going back on geodon. All I wanted to eat were swiss rolls and cheeseburgers. I think i gained 7-10 lbs that week. It's a bit fuzzy. I wasn't doing well at the time. I've been on almost all the meds this is the 2nd and 3rd time I've been on the meds I'm on now, but I had never been on this combo and amazingly it works. You can try a med again with a different combo and you might get different results. I think the med that saved my *** was equetro (carbamazapine) it's an extended release version of the med, but it's new and expensive.
